Should I add callout extensions to every campaign?

Should you add callout assets to every campaign?

Not by default. In most accounts, the best-performing (and easiest-to-manage) approach is to make sure every eligible ad has callout coverage, but that doesn’t mean duplicating callouts across every single campaign. Callout assets work best when they’re relevant, accurate, and scalable. If a callout applies broadly (for example, “Free shipping” or “24/7 support”), it’s usually smarter to set it once at the account level and let it cover everything it should.

Where advertisers get into trouble is treating callouts like a “checkbox optimization.” If you force campaign-level callouts everywhere, you often create unnecessary complexity, inconsistent messaging, and accidental conflicts where the platform can’t use your best callouts because you attached something more specific (even just one callout) at a lower level.

How callout assets really work (and why “every campaign” is the wrong default)

1) Level matters: account vs. campaign vs. ad group (and overrides are real)

You can attach callout assets at the account, campaign, or ad group level. The critical operational detail is that more specific levels override broader levels. In practice, that means if you add callouts at the ad group level, those ad group callouts can prevent your campaign-level callouts from being eligible for those ads. Likewise, campaign-level callouts can override account-level callouts for that campaign.

This is the main reason I don’t recommend blindly adding callouts to every campaign. If your goal is “coverage,” you can achieve that with strong account-level callouts. If your goal is “message control,” you should only go more granular when the campaign truly needs different promises.

2) Callouts don’t show on every impression (even if everything is set up correctly)

Adding callout assets doesn’t guarantee they’ll appear every time. Whether callouts show depends on factors like predicted performance, available space, and the overall competitiveness of the auction. If your ad rank/position isn’t strong enough, you may see fewer assets (or none) even when they’re approved and eligible.

That’s why I coach teams to judge callouts by incremental performance over time (CTR, conversion rate, and downstream lead quality), not by “I searched once and didn’t see them.”

3) There’s no fee to add callouts, but they can change how your ads compete

You’re not charged simply for having callouts. Charges still happen through normal ad interactions. In many cases, ads with strong assets earn more prominence and more engagement, which can be a win—but it can also mean your visible performance shifts (including CPC patterns) because your ad is competing differently.

The practical takeaway: callouts are usually a positive lever, but the objective isn’t “more assets everywhere.” The objective is “the right assets, where they belong, with clean measurement.”

A strategy that usually outperforms “add callouts to every campaign”

Step 1: Build evergreen account-level callouts for universal value props

Start by creating a small set of callouts that are true across your business and won’t change weekly. This gives you broad coverage without repeating setup work. Think of these as your “always-on trust and convenience stack.” Examples that often work well (when true): shipping/returns terms, availability, service guarantees, financing options, support hours, or experience signals.

Keep your callouts short and scannable. In most languages, you’re working with a tight character limit, so every word needs to earn its place. Also, avoid gimmicky punctuation or symbol-heavy callouts that try to “game” attention—those tend to create approval issues or simply underperform because they look less credible.

Step 2: Add campaign-level callouts only when the promise changes

Campaign-level callouts are ideal when a subset of campaigns has a distinct offer, audience, or fulfillment model that doesn’t apply everywhere. For example, maybe only one product line has “Same-day delivery,” only one region has “In-store pickup,” or only your clearance campaign legitimately has “Extra 20% off.”

If you’re tempted to add campaign-level callouts just because you can, pause and ask: Is this message meaningfully different from my account-level callouts? If not, you’re often better off leaving the campaign alone and letting your account-level assets do their job.

Step 3: Use ad group-level callouts for true exceptions (not for micromanagement)

Ad group-level callouts are powerful, but they come with a hidden cost: they can unintentionally block higher-level callouts from serving, which reduces the platform’s eligible pool to choose from. I reserve ad group callouts for scenarios where specificity is essential—like a product category with unique warranty terms, a service line with a different turnaround time, or a brand constraint that applies to only one theme.

Step 4: Give the system enough options—but keep them clean

Callouts are selected dynamically from the eligible pool, and only a limited number may show at once. You want enough variety that the platform can assemble the best combination for different queries, devices, and audiences—without flooding the account with near-duplicates.

In most accounts, a practical sweet spot is having at least 4 solid callouts available at the level you’re targeting (account or campaign), and often 6–10 if you have multiple strong, distinct value props. You can associate far more than that, but quantity stops helping once you’re repeating yourself or adding weak “filler” callouts.

When you actually should add callout assets to every campaign

There are a few cases where “every campaign gets its own callouts” is reasonable. It typically happens when you have distinct business lines living in one account and each line has different non-negotiable promises (shipping, returns, eligibility, compliance language, appointment requirements, etc.). Another common case is when different campaigns represent different locations or service models where a universal callout would be misleading.

Even then, my preference is to structure callouts so you’re not hand-building duplicates. If campaigns share a common truth, keep it higher level. If they don’t, go granular—but do it intentionally and consistently.

Critical diagnostic checklist (use this when callouts aren’t showing or aren’t helping)

  • Check level conflicts: If you attached even one callout at the ad group level, you may have unintentionally made your campaign-level callouts ineligible for that ad group.
  • Confirm approval status: Approved assets can serve; disapproved ones won’t. Fix disapprovals instead of duplicating new callouts that repeat the same problem.
  • Remove “attention hacks”: Overuse of punctuation/symbols, unnatural capitalization, or repetitive phrasing can cause issues and almost always reduces trust.
  • Ensure each callout is distinct: If you have five versions of “Free Shipping,” you’re not adding strength—you’re diluting the eligible pool with duplicates.
  • Improve eligibility conditions: If your ads rarely show any assets, it can be a position/ad-rank issue. Strengthen relevance (better intent alignment) and improve creative quality, not just asset quantity.
  • Watch scheduling and device settings: If callouts are scheduled too tightly (or set to mobile-only), you may have inadvertently limited when they can serve.
  • Make sure the promise is true for the traffic you’re buying: Misleading callouts don’t just create policy risk—they also create conversion-rate drag from mismatched expectations.

Bottom line: the best practice answer

If you want the strongest, lowest-maintenance setup: put universal callouts at the account level, then add campaign-level callouts only when the offer truly differs, and use ad group callouts sparingly for genuine exceptions. That approach typically produces better message consistency, fewer accidental overrides, and a healthier eligible pool for the platform to choose the best-performing callouts from—without turning your account into an asset-management nightmare.

Should I add callout assets to every campaign? No. Aim for full callout coverage across eligible ads, but don’t duplicate assets into every campaign by default. Use the broadest level that keeps messaging accurate and scalable.
  • Start with strong, evergreen account‑level callouts that apply to almost all campaigns (shipping, returns, support hours, guarantees, etc.).
  • Keep callouts short, scannable, and credible; avoid gimmicky punctuation or symbol “attention hacks.”
  • Focus on incremental performance over time (CTR, conversion rate, lead quality), not whether you see callouts on a single manual search.
  • Use campaign‑level callouts only when the offer, audience, or fulfillment model truly differs (for example, only one line has “Same‑day delivery” or “Extra 20% off”).
  • Use ad group‑level callouts only for real exceptions that need unique promises (for example, different warranty, turnaround, or legal/compliance language).
  • Avoid adding lower‑level callouts just because you can; each more‑specific association can override broader callouts.
  • Level conflicts: If you attach even one callout at ad group level, it can block campaign‑ or account‑level callouts from serving in that ad group.
  • Approval status: Confirm each asset is approved rather than duplicating disapproved messaging.
  • Asset quality: Remove symbol‑heavy, shouty, or repetitive callouts that hurt trust or violate policies.
  • Uniqueness: Avoid near‑duplicate callouts (for example, multiple versions of “Free Shipping”) that dilute the eligible pool.
  • Eligibility: If assets rarely show, investigate ad rank, relevance, scheduling, and device settings—not just asset quantity.
  • Truthfulness: Make sure each callout promise is accurate for the traffic that sees it to avoid policy risk and conversion‑rate drag.
How do asset levels (account, campaign, ad group) affect callouts? More specific levels override broader ones. Ad group callouts override campaign‑level callouts, and campaign‑level callouts override account‑level callouts for the same ad inventory.
  • Default to account‑level for universal value props so all eligible campaigns inherit them.
  • Guard against unnecessary lower‑level assets that fragment your eligible pool and reduce Google Ads’ flexibility in choosing the best‑performing combination.
  • Campaign‑level: when a campaign’s offer, pricing, or conditions are meaningfully different from the rest of the account.
  • Ad group‑level: for a small minority of cases where specific products, categories, or legal constraints require unique messaging.
  • Audit asset associations by level to confirm which callouts are actually eligible for each ad group.
  • Consolidate duplicate callouts back to higher levels where possible to simplify measurement and maintenance.
Why don’t callouts show on every impression? Even when correctly set up and approved, callouts are not guaranteed to show on every impression. Serving depends on ad rank, available space, predicted performance, device, and auction context.
  • Judge callouts based on incremental performance trends over time, not a handful of manual searches.
  • Ensure you have enough high‑quality, distinct callouts available so Google Ads can choose strong combinations.
  • Increase variety at the appropriate level: typically at least 4 solid callouts, often 6–10 distinct value props if truly different.
  • Avoid flooding campaigns with weak or repetitive callouts; more volume without quality doesn’t increase impressions.
  • Check whether low callout visibility coincides with low ad rank or limited eligibility.
  • Review device and scheduling settings to confirm you haven’t over‑restricted when callouts can appear.
  • About callout assets – notes eligibility conditions and the fact that multiple callouts may show depending on space.
  • Find your ad status – verify assets are eligible and not disapproved or limited in ways that block serving.
Is there any extra cost or risk to adding more callouts? There’s no direct fee for adding callouts; you still pay for normal ad interactions. However, stronger assets can change how often and where your ads show, which can shift CPCs and overall performance.
  • Treat callouts as a performance lever, not a free “checkbox” feature to apply everywhere.
  • Prioritize accurate, benefit‑driven callouts that improve click and conversion quality.
  • Expand callouts when you have genuinely new, compelling value props to test.
  • Pull back on noisy or misleading callouts that inflate clicks without improving downstream results.
  • Monitor shifts in CTR, conversion rate, and lead/sale quality when you add or change callouts.
  • Watch for policy limitations or disapprovals that could stop callouts from contributing as intended.
  • About callout assets – outlines benefits of callouts and how they can help performance.
  • Find your ad status – check for Approved (limited) or Disapproved statuses that might restrict impact.
When is “every campaign gets its own callouts” actually appropriate? Only when campaigns represent truly distinct business lines, locations, or service models whose promises can’t be accurately represented with shared account‑level callouts.
  • Define which messages are universal (keep at account level) and which are line‑ or location‑specific (at campaign level).
  • Standardize naming and structure so campaign‑specific callouts are intentional, not accidental duplicates.
  • Use campaign‑specific callouts for different shipping/returns policies, eligibility rules, compliance or legal language, or appointment requirements that vary by campaign.
  • If multiple campaigns share the same promise, move that callout back up to the account level for reuse.
  • Review all campaign‑level callouts periodically to merge duplicates and promote shared truths to the account level.
  • Confirm that no campaign’s callouts are misleading for part of its traffic (for example, mixed locations with different policies).
What’s the practical “bottom line” setup? The most reliable, low‑maintenance setup is: universal callouts at account level, campaign‑level callouts only when offers truly differ, and ad group callouts used sparingly for genuine exceptions.
  • Maintain a concise library of evergreen account‑level callouts that cover brand‑wide trust and convenience benefits.
  • Target a sweet spot of 4–10 strong, distinct callouts at the level you’re optimizing (account or campaign).
  • Periodically prune weak, outdated, or duplicate callouts to keep the eligible pool high‑quality.
  • Go more granular only if you can articulate a specific, different promise and measure its impact.
  • Avoid using ad group‑level callouts for micromanagement; treat them as exceptions with clear business justification.
  • Use a structured checklist when callouts aren’t showing or helping: level conflicts, approval, quality, uniqueness, eligibility, scheduling, devices, and truthfulness.
  • Align your measurement so you can compare performance before and after structural changes to callouts.

Not necessarily. A good rule is to aim for strong callout coverage across your eligible ads without copying the same assets into every single campaign by default: start with a small set of evergreen, account-level callouts (like shipping, returns, support, guarantees) that are true for most traffic, then only go more granular at the campaign or ad group level when an offer or fulfillment promise genuinely differs, since more specific levels can override broader ones and accidentally block other callouts from serving. Also remember callouts won’t show on every impression even when everything is set up correctly, so judge them on performance trends (CTR, conversion rate, lead quality) and keep an eye on approvals, duplicates, and “shouty” low-trust wording.
